Sodium chlorite (NaClO2) is a white crystalline solid that can accelerate the burning of organic substances. It is widely used in various industries, including paper manufacturing, water purification, wood pulp bleaching, textiles, fats and oils, as a disinfectant, and in many other fields. In organic synthesis, sodium chlorite is often used to convert aldehydes to carboxylic acids and alkyl furans to 4-oxo-2-alkenoic acids. Moreover, when combined with an acid such as citric acid, acidified sodium chlorite can be used to sanitize surfaces and rinse a variety of foods. In the military, sodium chlorite can be used to combat contaminants such as harmless microbes and food pathogens.

Product Application Of Sodium chlorite CAS#7758-19-2
Sodium chlorite is used in the in situ generation of chlorine dioxide for stripping of textiles, bleaching, pulp and paper industries. It acts as a disinfectant in water treatment plant and as a preservative in eye drops. It is also used in contact lens cleaning solution and for sanitizing air ducts. It is associated with zinc chloride and used as a component in therapeutic rinses, toothpastes, mouth sprays and gels. It is utilized for the synthesis of 4-oxo-2-alkenoic acids from alkyl furans. Further, it is involved as a reagent in Pinnick oxidation reaction to prepare carboxylic acid from aldehydes. |
